How to Troubleshoot Your Thermostat

A thermostat is a device that is critical to the operation of your heating, ventilation, and AC system. It regulates and manages temperature in the home in order to keep you comfortable. Unfortunately, things can go wrong with a thermostat and you may experience intermittent operation, or sometimes a complete breakdown. This guide is intended to help you troubleshoot and diagnose the common causes of a malfunctioning thermostat.

Check the Batteries

Thermostats that are battery operated may experience operational issues when the batteries are not changed on a regular basis. Batteries in a thermostat should be replaced at least every two years. Before doing anything else, check to see if the thermostat is battery operated and change the batteries if necessary.

Check the Thermostat Controls

If it is determined that your thermostat is not battery operated then you should check the thermostat controls to make sure that they are properly set. Look for any settings on your thermostat that may have been inadvertently changed and set it back to the previous settings.

If the settings were not changed, it is possible that the thermostat’s internal system has malfunctioned and needs to be replaced.

Check the Wiring

The next step to take if the thermostat has no battery operated system and the settings appear to be correct is to check the wiring. Most thermostats have three to five wiring connections that can be easily accessed. Loosen the screws and disconnect the wiring one at a time and inspect for any signs of corrosion, damage, or broken wires. Once any foreign objects have been removed, securely replace the wiring and make sure that it is properly connected.

Check Any Disruption in Power Supply

Thermostats can sometimes be affected by power surges or interruptions in the power supply. Check your circuit breaker or fuse box to ensure that the power supply to your thermostat is not being disrupted by an electrical fault.

Call aProfessional

If all else fails, it may be best to call in a professional to repair or replace your thermostat. Local reliable appliance repair technicians can help to diagnose and then fix a malfunctioning thermostat. An expert can replace the thermostat or repair any underlying issues.

When troubleshooting your thermostat, it is best to start with the basics and work your way up. Inspect and closely examine the batteries, settings, and wiring of your thermostat before calling a professional. By taking a few simple steps, you may be able to save yourself time, money, and prevent a complete breakdown of your AC or heating system. If all else fails, call a reputable appliance repair technician and they will help to get your thermostat up and running in no time! For local, reliable thermostat repair, call (866) 311-8590.
